Abstract (en)
[origin: US2015349288A1] Embodiments of the invention disclose a light emitting display panel. The light emitting display panel comprises a cover plate, a substrate disposed opposite to each other, a plurality of light emitting devices located between the cover plate and the substrate, and a packaging structure surrounding the light emitting devices. The packaging structure comprises at least three rows of protruded frames and a first packaging material which is located between adjacent protruded frames, wherein four sides of each of the protruded frames are looped and the at least three rows of protruded frames are adjacent to and embedded in each other in an inward and outward direction. Adjacent ones of the at least three rows of protruded frames are alternately disposed on the cover plate and the substrate and protrude in opposite directions, and non-adjacent ones of the at least three rows of protruded frames are disposed on the same one of the cover plate and the substrate and protrude in the same direction. In the above light emitting display panel, resin adhesive or desiccant is filled in gaps between the frames so as to prolong an invasion path of water vapor and oxygen gas spatially, an effect of preventing water vapor and oxygen gas is thus increased. The light emitting display panel has advantages of good sealing property, simple manufacturing process and the like.
